03 Ram 5.7 Hemi problems.

Correct me if I'm wrong, but that should have the dual plug heads with one plug having a coil pack and the other getting spark by a plug wire running from opposing cylinder? If a pair of wires are crossed, may do this and not throw a code. Also, the condition of the wires and the boots on the coil packs is something to look at. Had similar issue develop with my 05 Hemi Durango. Had a low rpm miss, but no codes. Threw plugs, wires, and boots on and we're good again.
